For printed electronics, fabrication of solution-processed organic semiconducting devices with high reliability is one of challenges. To overcome this issue, realization of directionally-controlled organic semiconducting single crystals for smooth carrier transport is key technology because organic semiconductor has anisotropic mobility. In this study, we investigated directional control of single crystalline C₈BTBT using solution-coated liquid crystal solution and photoalignment method and transistor characteristics.
